Overview
An absolute dial-gauge family designed to isolate the indicating movement from the process medium. Corrosion-resistant sensing and pressure-chamber components offer an alternative where a general-purpose capsule gauge is unsuitable.
Selection and installation
Tell us which chemicals and vapours are present, their concentrations and temperature, and the required pressure scale. We will check the wetted-material specification before quoting. Chemical-resistant does not mean universally compatible.
Questions about this instrument
What information is needed for chemical service?
Supply the process composition and cleaning agents as well as the operating conditions. Include the existing gauge model if this is a replacement.
Can I request calibration with my gauge?
Yes. Tell us the operating range, required test points and certificate requirement. We will confirm the calibration option for the selected instrument before quoting. Discuss vacuum gauge calibration.
Which related instruments should I consider?
Compare analogue vacuum transducers and vacuum gauge controllers. Check the pressure reference, measurement range and output rather than selecting by connection alone.
Where could this instrument be useful in a vacuum system?
Consider the required local vacuum indication when specifying the INDUSVAC centralised vacuum system or a SIRELLA dry-claw pump installation. Select the measuring range and pressure reference for the process, then confirm the connection and all wetted-material requirements. These links help plan an installation; they do not establish a direct-fit replacement.
Specify your requirement
Send the pressure range and reference (absolute or relative), process gas, connection, quantity and required delivery date. Include the existing model or a photograph for replacement enquiries.
